The component of Earth's atmosphere that is decreased due to photosynthesis is carbon dioxide (D).
mark me brainliest!!!!!
To develop the problem it is necessary to apply the equations related to the moment of inertia.
The given values can be defined as,
According to the definition of the moment of inertia applied to the exercise we can arrive at the equation that,
Where n is the number of spokes necessary to construct the wheel.
Replacing the values at the general equation we have,
Solving for n,
Therefore the number of spokes necessary to construct the wheel is 36
PART B) The mass of the wheel is given by the sum of all masses and the total spokes, then
Therefore the mass of the wheel must be of 1.36Kg
The electrical equivalent of one horsepower is 746 watts in the International System of Units (SI), and the heat equivalent is 2,545 BTU (British Thermal Units) per hour. Another unit of power is the metric horsepower, which equals 4,500 kilogram-metres per minute (32,549 foot-pounds per minute), or 0.9863 horsepower.
Answer: <span>D. A bimetallic strip bends so that the steel is on the outside curve

When something has an increased temperature, its volume will expand. Then, if the temperature drops, its volume should be smaller. From there option A and B are out since the liquid in thermometer is expand or move up.
When you put two kinds of different metal with a different coefficient of thermal expansion, the outer curve metal will be the one with lesser coefficient when temperature drop. Since the question about drop in temperature then the metal should be bend
Brass will expand 1.5 times more than the steel so the outer curve would be the steel.
